Steve's Notes

===== NGC 4650 24" (4/12/08 - Magellan Observatory, Australia): at 200x appeared bright, fairly large, round, strong even concentration with a very bright core inceasing to a small nucleus. A faint star is on the west side of the halo. NGC 4650A, a famous polar-ring galaxy, lies 5.6' ENE and PGC 42911 is a mere 1.9' E of center. The close companion appeared fairly faint, fairly small, elongated 2:1 ~E-W, 0.6'x0.3', even surface brightness. 48" (5/12/12): NGC 4650A appeared moderately bright, fairly small, oval 3:2 WSW-ESE, 24"x16". The polar ring was occasionally visible as faint, thin extensions oriented NNW-SSE. Need to reobserve as viewed through thin clouds. 17.5" (4/7/89): very faint, small, oval WNW-ESE, bright core. Appears slightly brighter than NGC 4622A 5.8' WNW. The unusual polar-ring galaxy NGC 4650A lies 5.6' ENE (not recorded). Member of the Centaurus cluster (AGC 3526).
